Abstracts Accepted and Presented at DFCon 08 in Hollywood this Past Week

PETALUMA, Calif.--(BUSINESS WIRE)--

Oculus Innovative Sciences, Inc. (Nasdaq:OCLS) announced that three abstracts, which relate to the safety and efficacy of Microcyn(R) Technology in the treatment of diabetic foot ulcers, were peer reviewed and presented at DFCon 08 this past week in Hollywood, California. The conference, which is one of the premier diabetic foot conferences in the world, is a showcase for the latest advances in the treatment and care of the diabetic foot. The three abstracts evaluating the use of the Microcyn(R) Technology were:

A 39-patient prospective and randomized study, "Efficacy and Safety of a Novel, Super-Oxidized Solution in Managing Post-Surgical Lesions of the Diabetic Foot," was led by Dr. Alberto Piagessi of the Azienda Ospedaliera Universitaria in Pisana, Italy. Diabetic patients with post-surgical infected lesions greater than 5 centimeters were randomized and received topical SOS (Microcyn in 20 patients) or povidone iodine (19 patients). Each group also received metabolic control, systemic antibiotics and offloading. At the endpoint of 24 weeks, 85% of the SOS (Microcyn) patients had healed versus 53% of the povidone iodine patients (p less than .01). The healing time was 10.5 weeks (+ or - 1.3 weeks) for the SOS (Microcyn) group versus 16.5 weeks (+ or - 1.7 weeks) for the povidone iodine group. No differences were observed in adverse events occurrence with two in the SOS (Microcyn) group and three in the povidone iodine group.

Investigator Conclusion: "Local treatment with SOS (Microcyn) proved to be as safe as and more effective than povidone iodine in the management of wide post-surgical lesions of the diabetic foot."

A 100-patient randomized trial entitled, "The Effect of Neutral-pH Super-Oxidized Solution for the Treatment of Infected Diabetic Foot Wounds" was directed by Amar Pal Sing Suri, DPM, a Harvard graduate and director of the Diabetic Footcare Center in New Delhi, India. Both type I and type II diabetic patients with solitary infected foot ulcers 2 to 15 centimeters were randomized into two groups. Each group was instructed to bathe their wounds in 20-50 mL of nSOS (Microcyn in 50 patients) or normal saline (50 patients) for 5 minutes, once per day for 16 weeks. Debridement was performed as needed. Patients were evaluated weekly by an examiner who was blinded to the solution being used for wound cleaning. All patients completed the 16-week study. A 5-log reduction in bioburden was documented in 76% of the nSOS (Microcyn) patients whereas only 32% of the patients in the saline group achieved a 2-log reduction in bioburden (p=0.01). At the conclusion of the trial, the wounds had healed in 78% of the nSOS (Microcyn) patients versus only 40% in the saline group (p=0.05).

Investigator Conclusion: "This study demonstrates that nSOS (Microcyn) is superior to saline for treating mildly infected foot wounds in diabetic patients and that mechanical eradication of bacteria is not the sole explanation of its efficacy."

A 23-patient study, "Wound Healing in Chronic Lower Extremity Wounds Comparing Super-Oxidized Solution vs. Saline," was overseen by Robert G. Frykberg, DPM, MPH, of the Carl T. Hayden VA Medical Center in Phoenix, Arizona. Diabetic patients were enrolled in this open-label study and consecutively assigned 1:1 to either SOS (Microcyn) or saline treatment. Local standard of care included debridement, off-loading and daily wound care. Patients were followed weekly for two weeks and were monitored for wound size, extent of epithelialization and other clinical assessments. In this preliminary report, clinically evaluable patients included 13 in the SOS (Microcyn) group and 10 in the saline group with wound size of 3.06 vs 1.56 centimeters respectively. All patients had diabetes and most wounds were present for at least 7 weeks. At week 1, median wound size had decreased 45% to 1.68 cm with 3 wounds 100% epithelialized in the SOS (Microcyn) arm versus 19% reduction in size to 1.26 cm and no wounds 100% epithelialized in the saline group. At week 2, 2 wounds were cured and 9 were 100% epithelialized in the SOS (Microcyn) Group compared to 0 cured and only one 100% epithelialized in the saline group. The study will continue to complete the enrollment of 20 patients in each arm.

Investigator Conclusion: "These preliminary data suggest that daily use of SOS (Microcyn) may promote wound healing in chronic wounds when compared to saline."

Andres A. Gutierrez M.D., Ph.D., director of medical affairs of Oculus Innovative Sciences, said, "The positive results from these abstracts continue to support the experience we have had with nearly one million patients worldwide and the data we have seen in 23 other studies on over 700 patients--most recently in our U.S. Phase II trial in which Microcyn demonstrated a positive clinical response with a 93% cure or improvement of infection in diabetic foot ulcers in the final follow-up visit. These consistent results are very encouraging since in the second arm of this study we are compared to a highly respected antibiotic in levofloxacin, which demonstrated only a 56% clinical success rate during the same visit. Now we see our next major milestone being further analysis of the Phase II trial as we prepare for our end-of-Phase II meeting with the FDA and another step towards a new drug approval in the United States."

Oculus presented additional results from the recently completed U.S. Phase II trial assessing the safety and efficacy of the Microcyn Technology in the treatment of mildly infected diabetic foot ulcers via a teleconference at DFCon 08 as well. (http://www.oculusis.com/phase2data_update/).
